Pelvic girdle pain typically feels like a deep ache or sharp, shooting sensation centered around the pelvis, often at the front of the pubic bone, the back of the pelvis near the tailbone, or both. It affects roughly 44% of pregnant women, though it can also occur outside of pregnancy. The pain ranges from a mild stiffness to a stabbing feeling intense enough to make everyday movements like walking or rolling over in bed genuinely difficult.
Where You Feel It
The pain doesn’t stay in one neat spot. It can show up in several areas at once or shift between them. The most common locations are the pubic bone at the front center of the pelvis (the symphysis pubis joint) and the sacroiliac joints, which sit deep in the lower back where the spine meets the pelvis. But pain also commonly radiates into the groin, buttocks, hips, outer thighs, and the front or back of the upper leg. Some people feel it in the pelvic floor as well.
Pain at the front of the pelvis tends to feel sharp and localized, right over the bone. Pain at the back often feels deeper and may favor one side, spreading into the buttock or down the back of the thigh. You can have one pattern or both simultaneously.
The Specific Sensations
People describe pelvic girdle pain in a few distinct ways depending on which joint is involved. At the pubic bone, it’s often a sharp, shooting pain that flares when you lift a leg, get out of a car, or turn in bed. At the sacroiliac joints in the back, it tends to be a deep, heavy ache that worsens with sustained activity.
One hallmark that surprises many people is an audible or felt clicking or grinding sensation from the pelvis. This mechanical symptom is especially common with symphysis pubis dysfunction and can happen when you walk, shift your weight, or change positions. It sounds alarming, but it reflects instability in the joint rather than structural damage. The grinding doesn’t necessarily correlate with how severe the pain is. Some people hear it frequently with only mild discomfort, while others have intense pain with no clicking at all.
What Makes It Worse
Pelvic girdle pain is closely tied to movement, particularly any activity that loads one side of the pelvis at a time. The Royal College of Obstetricians and Gynaecologists identifies these common triggers:
- Walking, especially on uneven ground or for long distances
- Climbing stairs, which forces you to stand on one leg repeatedly
- Rolling over in bed, one of the most frequently reported triggers
- Getting in and out of a car, which requires spreading the knees apart
- Standing on one leg, such as when dressing or stepping into a bath
- Lifting heavy objects, including carrying a toddler on one hip
Sitting or standing for long periods can also provoke it, as can sitting on the floor or in a twisted position. Sexual intercourse is another common trigger. The pattern is consistent: anything that asks the pelvis to bear an asymmetric load or spread the joints apart tends to flare the pain. Many people notice the pain is worst at the end of the day after accumulated activity, and that it eases somewhat with rest.
How It Differs From Sciatica
Because both conditions can cause pain in the buttock and back of the thigh, pelvic girdle pain and sciatica are easy to confuse, especially during pregnancy when both are common. The key differences come down to the type of sensation and how far the pain travels.
True sciatica involves compression of the sciatic nerve and produces a sharp, electrical shooting pain that travels down the back of the leg, often past the knee and into the calf or foot. Numbness, tingling, or a “pins and needles” feeling along a clear path down the leg is characteristic. Pelvic girdle pain, by contrast, rarely travels below the knee. It stays centered around the pelvis and upper thigh, and the sensation is more of a deep ache or sharp joint pain rather than an electrical or burning nerve pain. If you’re feeling numbness or tingling in your lower leg or foot, that points more toward a nerve issue than pelvic girdle pain.
There’s also a third possibility called piriformis syndrome, sometimes called pseudo-sciatica, which causes a dull, deep ache or burning sensation localized to the buttock and upper hamstring. It lacks the severe shooting quality of true sciatica and the joint-centered quality of pelvic girdle pain.
Severity and Daily Impact
The intensity varies widely. For some people, pelvic girdle pain is a manageable annoyance, a stiffness when getting out of bed that loosens up after a few minutes. For others, it becomes disabling. Women with moderate to severe cases report difficulty with basic tasks: grocery shopping, playing with children, working at a desk, even sleeping through the night because turning over triggers a jolt of pain.
The pain can also change how you move. Many people develop a waddling gait or take smaller steps instinctively to avoid triggering the sharp sensations. Stairs may require a step-by-step approach rather than alternating feet. These compensations are your body’s way of protecting the unstable joints, but they can lead to muscle fatigue and soreness in the hips and legs over time.
How Long It Lasts
If your pelvic girdle pain is pregnancy-related, the trajectory is generally encouraging. Pain and physical function improve markedly in the first 12 weeks after delivery. For most women, the worst of it resolves in that initial postpartum window as hormone levels normalize and the joints restabilize.
However, the recovery isn’t always complete. Research tracking women from late pregnancy through the first year postpartum found that about 30 to 31% still reported pelvic girdle pain at both 12 weeks and one year after giving birth, suggesting that once symptoms persist past the initial recovery window, they tend to plateau rather than continue improving on their own. A longer-term study found that 8.5% of women who had pelvic girdle pain in late pregnancy still reported it two years after delivery.
For non-pregnancy-related pelvic girdle pain, the timeline depends more on the underlying cause. Conditions like sacroiliac joint dysfunction or pubic symphysis instability from injury or hypermobility can be longer-lasting, but most respond well to physical therapy focused on stabilizing the pelvis and strengthening the surrounding muscles.
What Helps
Physical therapy is the most consistently effective approach. A physiotherapist can teach you exercises that strengthen the muscles supporting the pelvis, particularly the deep core and gluteal muscles, which help compensate for joint instability. They can also show you movement modifications that reduce strain, like keeping your knees together when rolling in bed or using a plastic bag on the car seat to make swiveling in and out easier.
A pelvic support belt worn low around the hips can provide some relief by compressing the joints and reducing the movement that triggers pain. Ice or heat on the affected area helps manage flare-ups. Sleeping with a pillow between your knees keeps the pelvis aligned and reduces the pulling sensation on the pubic bone.
Activity modification matters as much as any treatment. Avoiding stairs when possible, sitting down to get dressed, breaking up long walks into shorter segments, and skipping heavy lifting can meaningfully reduce how much pain you experience day to day. The goal isn’t to stop moving entirely, which can actually worsen stiffness, but to stay active within a range that doesn’t consistently provoke sharp pain.
